9.2.1.2.1 Inductor Selection
To properly configure the TPS6126x devices, an inductor must be connected between the VIN pin and the L pin. Equation 3 is used to estimate the minimum inductance value for accurate average output current regulation; the inductor current should be continuous.
In Equation 3, the minimum inductance value required for accurate average output current regulation is calculated. VIN is the input voltage. For typical applications which require voltage regulation, the recommended inductor value is 4.7 μH. Applications with higher inductance values have lower light load efficiency. The recommended range for the inductor value is from 2.2 μH up to 22 μH. The current rating required for this inductor is ILIM and depends on the programmed output current IOUT. Please refer to the Electrical Characteristics. Table 3 contains a list of inductors recommended for the TPS6126x:
